Using passwords
A password is a group of characters that you choose to secure computer information. Several types of
passwords can be set, depending on how you want to control access to your information. Passwords
are set in Windows or in the non-Windows Setup Utility preinstalled on the computer.
CAUTION: To prevent being locked out of the computer, record each password set. Because most
passwords are not displayed as they are set, changed, or deleted, it is essential to record each password
immediately and store it in a secure place.
